Effects of Oxides of Nitrogen
• On the Environment:
Oxides of nitrogen, particularly Nitrogen Dioxide, when in excess, hamper the growth of plants, damage their leaves and roots, and may even cause death. Excessive levels also cause acid rain, as, when in the atmosphere, oxides of nitrogen are oxidized to Nitrogen Dioxide, which then dissolves in water, producing dilute Nitric acid, which then precipitates in rain (shown in reaction below). Acid rain, would in turn, affect the pH level of structures, but mostly soil and water, thus affecting the ecosystem, as the right pH condition of the soil is a component which determines the growth and abundance of plants, the very base of the food chain.
Acid Rain: 2NO2 + H2O -> HNO2 + HNO3
